>>> we're learning more tonight about the health challenge for bo biden, the son of the vice president, who is also the attorney general of delaware . we learned today that emts were called to the house two weeks ago to help someone in distress, and we know he went in for a procedure last night at a top cancer center in houston. chief medical editor dr. nancy snyderman is here. what do we know about this tonight?
>> we know how he was admitted to m.d. anderson cancer center and underwent a procedure last night, what is being described as a complicated biopsy. you can read from that that it's likely that there was a tumor or some type of tissue left behind from this mass that was biopsied. we do know e that he had a restful night. there have not been any complications, which means he's expected to go home tomorrow. but these can be frustrating times for families because families want answers, and sometimes if there's a complicated biopsy, it means you just don't have enough tissue to really make a definitive diagnosis, so now it will be days or weeks until that diagnosis is made and i can guarantee you the doctors between m.d. anderson and his doctors in philadelphia will be talking and sharing information daily to try to figure out exactly what this is. perhaps this procedure he had will take away the risk of stroke that he's had and then form late a really strong plan going forward.
